2 1/10 grams
To find the mass of one ball, we need to divide the total mass of the 3 balls by 3.
Given that the total mass is 6 3/10 grams, we can convert it to an improper fraction:
6 3/10 = (6 * 10 + 3)/10 = 63/10
Now, divide 63/10 by 3:
63/10 ÷ 3 = 63/10 * 1/3 = 63/30 = 21/10
Now, convert 21/10 back into a mixed number:
21/10 = (2 * 10 + 1)/10 = 2 1/10
Therefore, the mass of one ball is 2 1/10 grams.
The correct answer is 2 1/10 grams.
To find the mass of one ball, we need to divide the total mass of the 3 balls by 3.
The total mass of the 3 balls is 6 3/10 grams, which can be written as 6 + 3/10 = 60/10 + 3/10 = 63/10 grams.
Now we divide 63/10 grams by 3:
(63/10) / 3 = 63/10 × 1/3 = 63/30 = 21/10 = 2 1/10 grams.
Therefore, the mass of one ball is 2 1/10 grams.
To find the mass of one ball, you need to divide the total mass of the three balls by the number of balls. In this case, the total mass is 6 3/10 grams, and there are 3 balls.
Step 1: Convert the mixed number 6 3/10 to the improper fraction form:
6 3/10 = (6 * 10 + 3)/10 = 63/10
Step 2: Divide the total mass by the number of balls:
63/10 ÷ 3 = (63/10) * (1/3) = 63/30 = 21/10
Step 3: Simplify the fraction, if possible:
21/10 = (2 * 10 + 1)/10 = 2 1/10
Therefore, the mass of one ball is 2 1/10 grams.
